This invention relates to a telesco ic umbrella of the kind wherein the stretc era are pivoted to the outer rib sections and wherein the stretchers are supported by auxiliary strum, and the invention consists essentially. in connecting one end of each strut pivotally to the central portion of the stretcher and arranging the other end to slide on the corres ending inner rib section.

is man ement has the advantage that the struts wil not be hindered in their movement by the stick sections on the closing of the umbrella. The tubular handle, more-' over is adapted, by engagement with the ribs on the umbrella being collapsed, to preventthe struts from coming into contact with andfoul the stick sections.

In order to retain the runner and the ribs in their proper ositions on the umbrella being collapsed, t e runner and its catch are adgpted to move together into the handle.

The umbrella comprises rib sections and 17 the latter of which are ivoted to the crown 22 and provided at teir free ends with sleeves 18 wherein the ribsections 15 are slidabl guided. The section 15 moves inside the c annel section 17 and is connected at 16 to a saddle-piece 19 which embraces and slides'onthe section 17. The stretchers 14 are pivoted at one end to the saddle-pieces 19 and at the other end to the runner 11. Connected'to the centre portion of each stretcher 1411s a bracket 20 to which one end of an aux- 'iliary strut 21 is pivotally attached. The

other end of the strut is pivoted to a sleeve 45 23 which is free to slide on the inner section 17 of thecorresponding rib. The struts are resilient and each strut is, as described and claimedin'the co-pending application Serial No. 475,647, filed August 16, 1930, formed with a knee '24 which, when the umbrella is PLATE N'r ,orr cs V exam UHBBILTJ. v I

closed, bears against and exerts outward pressure on the contiguous stretcher, thereby facilitating the spreading a art of the ribs and the openmg out of the um rella. As the umbrella is opened, the sleeves 23 move up the rib sections 1 until they strike against the crown 22, and thereuponthey act on the stretchers so as to effect the complete extension of the rib sections 15. I

The stick is com osed of telescopic sections 27, 1, 2 and 3 which are locked in extended position by catches 26, 25 and 13. The catch 13 is released by hand, and the catches 25 and 26 are released'by the thrust of the stick sections 3 and 2 respectively to allow the. stick to collapse. The catch 26 also serves to retain the runner and maintain the umbrella in open position, it being depressed by hand for the release of the runner. A pin 29 connected to the stick section 1, extends through a slot 28 in the section 27 and limits the movements of the latter. The head of this pin also serves as a stop for the runner 11. Connected to the lower end of the stick sec tion 3 is a tubular handle 4 which is adapted, 7 on the stick bein collapsed, to slide over the runner 11 and ri e between the stretchers 14 and the ribs 15. The latter, by abutment against the handle 4, prevent the struts 21 from coming into contact with the stick sections, thus leaving'the latter full freedom of movement and protecting them from being damaged by abraison.

The spring 12 which controls the catch 13 also controls a catch lever 9 which is 1v- 35 oted at 8 inside the stick section 2 and w ich is adapted to engage and retain the runner 11 on the umbrella beinglclosed. The catch 9,, which rejects throng slots in the sections2 and 3, has a bevelled head 10 which is auto- 90 matically retracted by the runner on the lowering of the latter and which sna s into angagement therewith. The slot 7 m thesection 3 is long enough to enable the runner and catch to move together into the handle 4 when the umbrella is collapsed. [Thus the runner and ribs will be retained in their proper positions during this operation.

In the'construction shown in Fig. 1, the

handle 4; is adapted to slide over a piston-like member 5 which guides it and causes it to act uniformly on all the stretchers. The member 5 is connected to the inner section 2 by means of a pin-6 which extends through it 6 and is guided in the slot 7 in the outer section 3.

In the construction shown in Fig. 4, the member 5 is-omitted and the stick section 3 is screwed into a boss-30 mounted inside the I!) handle.

I claim: -1. In an umbrella having a telescopically adjustable rib ivoted to a crown and astretcher pivote to the outer rib section, an llauxiliary strut pivoted at one end to the stretcher and slidable at the other end on the inner rib section independently of the outer one.

2. A structure as claimedin claim 1 where- .20 in the auxiliary strut is adapted to bear against the crown when the umbrella is 0 en.
